Chapter 590

Zhang Yuan recalled the past and suddenly found that every progress of civilization was at the cost of the sacrifice of some people.

They also talked about the black technology that had appeared. In addition to nuclear weapons, addictive drugs and the virtual world, there is actually another black technology that has been ignored by mankind, that is, toxic fuel.

What is toxic fuel? That is, the propellant of the rocket. If we only look at the chemical principle, the most ideal is fluorine fuel. For example, fluorine reacts with hydrogen to produce hydrogen fluoride, which releases a lot of energy.

But this thing is highly toxic! Skin contact with tens of milligrams requires amputation, and hundreds of milligrams can't be saved directly. You can prepare for the future.

The fuel of Long March 5 is about 800 tons. It is launched once with fluorine. If it is accidentally leaked, it can kill hundreds of millions of people.

The size of Saturn V can bring humans together!

Organic compounds such as pentaborane and methylmercury are also often used as fuel additives. According to the early design, hydrazine fuel should be used in conjunction with mercury. If the fuel for launching a rocket leaks, it can pollute the territory of a province.

So why do you want to do such a dangerous thing? Because without these things, the rocket thrust is not enough and can't go at all.

In the 1970s, it was such a competitive and somewhat sad era. Everyone was frightened to launch rockets in the field for fear of large-scale pollution after failure.

Fortunately, mankind has walked through the most dangerous time, aerospace technology is also developing from generation to generation, and toxic fuel has long been abandoned and turned into hydrogen and oxygen fuel.

Even rocket technology has been slowly abandoned

With the emergence of curvature engine, human beings naturally move towards a higher sky and become a real four-level civilization.

Zhang Yuan looked at the starry sky on the dome of the cafe and stretched lazily, as if embracing the future.

No, already embracing the future!

A new era is slowly pulling out the prelude

……

With the birth of curvature technology, human footprints will spread all over the corners of the planetary system in a few years!

If you put it in the past, it would take several years to move from one planet to another on the edge of the planet just relying on the slow ion engine. It is impossible to explore every planet here without hundreds of years.

Thanks to the new means of transportation, a large number of explorers yearning for distance have appeared in the human group, who have found the best scenery of this planetary system.

For example, a large comet named "baribaga bar" is composed of rocks and ice. Its color is like a super large cream cake, especially the side facing away from the sun, which is steep like a pink cut cake!

Many young people like to climb on the "cut cake" to take pictures.

There is also a planet called "midalas", which has a very strong magnetic field. The solar wind blown by the star often marks a brilliant Aurora above its atmosphere.

In fact, humans do not intend to settle in this place for a long time, so most planets will not be developed. Instead, they provide natural exploration places for these tourism lovers

"... please note that we are now arriving at the site of the second branch of new humanity. Please put on your spacesuit and get off the spaceship in order. "

This is the planet selected by the once brilliant branch of the galaxy. Because the gravity environment of this planet is similar to that of the earth, it will be more comfortable for humans to live on it, so the base camp of the whole new human civilization has long been replaced by a planet.

Humans live at one end of the planet, and the ruins of the original second branch, at the other end of the planet, have gradually become a tourist holy land.

Here, people can see these gradually dilapidated sites and experience the stories that have happened.

Zhang Yuan and Lin Xuanxuan came to this human site during a rare holiday.

"Did you expect this to happen at that time?" Seeing the devastation, Lin Xuanxuan asked in a low voice.

Zhang Yuan was stunned. "What if you expect... The power of an era will not change because of prediction. What should happen will still happen. But now, the result is good. We have to look forward. "

Lin Xuanxuan asked suspiciously, "since you expected this possibility, why don't you take some measures to stop it? Have you expected it to happen? "

Zhang Yuan shrunk his neck and sighed: "it's hard to say that the decline of a human branch is not meaningless..."

Most of the people coming and going around are middle school students and primary school students. Many people are very excited when they go out of school for the first time. But when they entered the site, they dared not make a sound.

His voice gradually lowered: "it will only make us move forward more steadily."

"Why? Can you tell me? " Lin Xuanxuan knows that her husband is the kind of person who is very cruel to big things. Most of the time he is very friendly, but for a small part of the time, human life is just a number for him.

"Why..." Zhang Yuan thought, "at that time, several of our old guys suddenly found that no, human beings will degenerate... Later, they found that this is actually better. It's no big deal."

"First, you see, at present, our population has expanded to 100 million. With this happening, this 100 million population has become a high-quality population with upward ideology."

"This kind of high-quality population can not be produced by simple education."

"Second." His voice became more hoarse: "in the future, this group of people will have a higher probability of passing the examination of extraordinary people. Even one percent, there are a million extraordinary people. That's really good. "

"Therefore, if this matter does not produce the best, it will produce... There must always be someone to illuminate the road ahead. The fourth level of civilization is far from the focus. "

Lin Xuanxuan stopped talking and just sighed.

The site was not deliberately repaired. It was allowed to decay so slowly. There was more and more dust and rust. The only electric lights were very dim.

It is the first time that children have felt this power from time.

The teachers are handing out cleaning tools for them to clean.

There is also a hibernation warehouse ahead. A woman is frozen in it like a sleeping beauty with a faint smile on her face. It is stated in the will that she put it here voluntarily to provide lessons for later generations. She is a good person and a bad person.

When children see these eternal hibernators, they have a real fear

This is a real fear, beyond my instinct.

"She will never wake up. It's like having a beautiful dream..." Lin Xuanxuan said slightly sadly, "what is human self-consciousness?"

"It should be a randomness that can create information..." Zhang Yuan, as an expert in this field, has his own explanation: "simple information will not create more information. The generation of information must come from the real reality."

"Randomness, that is, a way of generating information, is a kind of reality. Self awareness must be combined with existing information to give birth to real human information. "

"So, after losing her will, this person looks like a vegetable, because her brain can't create more information of her own."

"Because randomness is a kind of reality, we now think that the virtual world is also real, so it can give birth to new life."

Zhang Yuan paused and said, "now the fantasy laboratory is trying to study a kind of pseudo-random, that is, to install a part of robot software into the human brain."

"At that time, these vegetative people will be able to 'resurrect' again. They can run, jump, talk and sing. But they are all weak artificial intelligence without randomness. Human beings can't distinguish them under normal conditions. It's called pseudo human for short. "

Lin Xuanxuan could not help shivering. She had an instinctive psychological attack. Looking at her husband, she looked like a crazy scientist.

This kind of research... Certainly has significance.

She patted Zhang Yuan. The power armour made a "bang" and asked, "are you a legendary... Fake person? You have to tell me how to distinguish between real people and fake people who sleep with me? "

"It's a fake. Really, I've used the first generation of high technology!"

Zhang Yuan felt that he was joking a little too much and hurriedly ran away
